llviPRovEMENT IN v|sEs.

Specification forming part of Letters Patent No. 119,280, datedSeptember 26, 1871.

To all whom it may concern:

Be it known that I, RUSSELL PHILLIPS, of Boston, in the county ofSuffolk and State ,of Massachusetts, have made an invention of a new anduseful implement or tool which I denominate a Carpenters Combined Viseand Hand-Saw; and do hereby declare the following to be afull, clear,and exact description thereof, due reference being had totheaccompanying drawing making part of this specification, and in which-Figure 1 is a side elevation; Fig. 2, a vertical and longitudinalsection; Fig. 3, a rear-edge View; and Fig. 4, a longitudinal section ofmy invention.

The drawing represents at A one leg of a vise, the upper end or jaw of'such leg being shown at B, while extending rearward from it is ahorizontal shelf or abutment, C, for supporting, in connection with asliding jaw, 4(hereinafter mentioned) the vise upon a bench, thisconstruction of one portion or leg of a vise being substantially thesame as in many now in use. The opposite and (when used as a bench-vise)outer leg is shown at D, and its jaw at E, such leg being fulcrumed to abracket or arm, F, extending horizontally from the primary jawT at itscenter, or thereabout, this outer leg -D and its jaw being operated by ascrew, G, screwed through its lower end and abutting' against theadjacent end ofthe former, by which great leverage is obtained to forcethe two jaws B and E together. In order to obtain wide-variations in thedistance intervening between the two jaws B and C in adapting objects ofconsiderably different bulk thereto, a series 'of holes, a c, is formedin the offset or bracket F which supports the oscillating jaw D, thefulcrum b being changed from one to the other as occasion requires. H intheaccompanying drawing represents a flat plate sliding upon therearface of the leg A and confined thereto in a suitable manner, theouter edge of such plate being fashioned into a toothed rack,

I, while its upper extremity is provided with a irearwardright-angularextension or abutment,

J which, in conjunction-with the abutment C of' the leg A whichSurmounts it, produces a handscrew or clamp for carpenters use. Thisabutment or clamp-jaw J may be swiveled to the plate H inorder to adaptthe parts to irregular or tapering objects, and,` in fact, should be somade; and, whether rigid or oscillating, serves,

in conjunction with the abutment C, as a means of securing the wholedevice to a bench. K in the drawing denotes a furcated, curved, or S-shaped lever, the fulcrum of which is a pin, c, passed horizontallythrough it and the lower extremity of the primary leg A, the lower endor the base of such lever straddling the rack I and carrying anoscillating driving-pawl, M, which is pivoted to it in such manner as totake into the teeth of the rack when ascending, and to slip over thesame when descending. The upper and front end or handle of' the lever Kencompasses the movable jaw or leg D of the instrument, and is providedat its outer extremity with a screw, N, which passes through and abutsagainst the bracket F which supports the said movable jaw, the length ofthe lever K being sufficient for the purpose. Owing tothe short distancebetween the base and fulcrum of' the lever K and the length of' itshandle, I am enabled by the use of the screw N to exert 'a very powerfulaction upon the rack I, and to clamp an object between its jaw and theabutment C with a great pressure by the expenditure of very little poweron the part ofthe artisan. To effect extended depressions of the plate Hor itsrackI forthe purpose of adapting the hand-screw of' which itconstitutes, a part to objects of varying capacity, the pawl L is to bedisengaged from such rack, when bothrack and jaw will drop of their ownaccord, or may be lowered or forced away f'rom the abutment C asoccasion requires. The rack and its jaw may be elevated or advancedtoward the movable jaw without regard to or manipulating thepawl. Theabove description will, it is believed, afford an explanationsufliciently lucid to enable mechanics to make, understand, and use theinvention to which it relates.

vThe advantages of my present invention are several and manifest: First,when used as a hand-screw or clamp the abutments or jaws C and J adaptthemselves (especiallywhen thelatter is pivoted to the plate H)automatically to ir-v possible with the present hand-screw, so called.Second, my improved combination instrument may be used at pleasureeither as a hand or benchvise. Third, while I am enabled to obtain anextended and rapid movement of the leg D, .I am, A

enabled, by the mode herein adopted of pivoting and operating it, toforce it toward the primary jaw B with a very great increase of powerover that possible to be attained by pivoting it at its lower end andoperating it by direct and sole action of a screw. Fourth, ashereinbefore alluded to, I obtain in one instrument, the functions of ahand-screw or clamp, and a vise-either a hand or bench-vise. Fifth, I amenabled to produce the above combined instrument in castiron at anexpense not exceeding that of an ordinary hand-vise and much below thatof a benchvise. Sixth, the form and arrangement of the forth.
